SQL & PL/SQL :: How To Avoid Duplicate Rows From Being Inserted In The Table

Dec 21, 2009

I have one table in which I want to restrict some records from being inserted. I don't want to put any checked constraints. e.g. consider following table

transaction(
id number primary key,
txn_date timestamp(7),
payee varchar2(40),
amount number,
memo varchar2(40),
ref_num number
)

I want to write SQL which should not inset duplicate record.

e.g.

I have written one as bellow:

insert into transaction
select 1, to_date('2009-12-12','YYYY-MM-DD'), 'Payee1', 12, 'Test', 212 from dual where
(select count(*) from transaction where txn_date=to_date('2009-12-12','YYYY-MM-DD') and
payee='Payee1' and amount=12)=0;

Can I use exists/not exists, which query will be more appropriate. (Please consider that fields which I am using to filter out the duplicate transactions does not contain primary key.)

Can I write such SQL. Or do i check for duplicate rows one by one and then filter the duplicate records.

Application Express :: What Would Cause Oracle To Insert Duplicate Rows Into A Table

May 2, 2013

What would cause Oracle to insert duplicate rows into a table? Could a join of two tables in the initial query assigned to an application page cause ORacle to insert an extra row into a table when an update to data value occurs? I have no insert triggers and no foreign keys assigned to the table. I am not sure what would cause Oracle to assume that an insert of a row must occur. I want to prevent that insert.

PL/SQL :: Duplicate Rows Removal

Jul 3, 2012

removing duplicate rows from a table.

We have the following table:

SSD@ermd> desc person_pos_history
Name Null? Type
------------------------------------------------------------------------ -------- ------------------------

PERSON_POSITION_HISTORY_ID NOT NULL NUMBER(10)
POSITION_TYPE_ID NOT NULL NUMBER(10)
PERSON_ID NOT NULL NUMBER(10)
EVENT_ID NOT NULL NUMBER(10)
USER_INFO_ID NUMBER(10)
TIMESTAMP NOT NULL DATE

We found out that few person_id's are repeating for a particular event (3):

select PERSON_ID, count(*)
from person_pos_history
group by PERSON_ID, EVENT_ID
having event_id=3
and count(*) > 1
order by 2

PERSON_ID COUNT(*)
---------- ----------
217045 356
216993 356
226198 356
217248 364

[Code]...

If we look at the 1st person id "217045", we can see that it is repeating 356 times for event id 3.

SSD@ermd> select POSITION_ASSIGNMENT_HISTORY_ID, POSITION_TYPE_ID, PERSON_ID,EVENT_ID, to_char(timestamp, 'YYYY-MM-DD HH24:MI:SS')
2 from person_pos_history
3 where EVENT_ID=3
4 and person_id=217045
5 order by timestamp;

PERSON_POSITION_HISTORY_ID POSITION_TYPE_ID PERSON_ID EVENT_ID TO_CHAR(TIMESTAMP,'
------------------------------ ---------------- ---------- ---------- -------------------
222775 38 217045 03 2012-05-07 10:29:49
222774 18 217045 03 2012-05-07 10:29:49
222773 8 217045 03 2012-05-07 10:29:49

[Code]...

356 rows selected.It is safe to assume that the person id/event id with the earliest timestamp is the one that was loaded 1st, hence, the one we want to keep and the rest should be deleted.

sql to achieve the duplicate removal.

SQL & PL/SQL :: Joining But Avoiding Duplicate Rows

Oct 16, 2010

I have two tables A and B

CREATE TABLE A(EMP_ID NUMBER, EMP_NAME VARCHAR2(100))
CREATE TABLE B(EMP_ID NUMBER, EMP_ATT1 VARCHAR2(10), EMP_ATT2 VARCHAR2(10))
INSERT INTO A VALUES(1, 'ONE');
INSERT INTO A VALUES(2, 'TWO');
INSERT INTO A VALUES(3, 'THREE');

[Code]....

This query returns all the matching row of A and B

SELECT A.EMP_ID, A.EMP_NAME, B.EMP_ATT1, B.EMP_ATT2
FROM A
INNER JOIN B ON A.EMP_ID=B.EMP_ID

The output for this shows:

EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2
1 ONE 1ATT1 1ATT2
2 TWO 2ATT1 2ATT2
2 TWO 2ATT1.1 2ATT2.1
3 THREE 3ATT1 3ATT2

The requirement is to avoid duplicate rows even if matched:

EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2
1 ONE 1ATT1 1ATT2
2 TWO 2ATT1 2ATT2
3 THREE 3ATT1 3ATT2

Duplicate Sequence Number For Identical Rows

Jul 5, 2010

I have a table:

Name
_____
Smith Street
Smith Street
John Street
Ed Street
Ed Street
Ed Street

and need to assign sequence numbers only when the record (Name) changes, e.g. :

Name Seq
_____ ____
Smith Street 1
Smith Street 1
John Street 2
Ed Street 3
Ed Street 3
Ed Street 3

I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.

If I grouped the records by Name I would like to have unique, sequential numbers: 1, 2, 3 but where there is the same name I would like the sequence to stop and the number to replicate?

SQL & PL/SQL :: Removing Duplicate Rows When Condition Is Matched

Mar 17, 2010

My requirement if id, join_date, join_time, result of table1 is matched with table2 at least one time then if repeating rows associated with the id should not come.Here is the test case.

create table table1
( id number , join_date varchar2(8), join_time varchar2(6), status varchar2(10));
create table table2
( id number , join_date varchar2(8), join_time varchar2(6), status varchar2(10));

insert into table1 values (01, '20010101', '0500', 'PASS');
insert into table1 values (01, '20010102', '0501', 'FAIL');
insert into table1 values (02, '20010103', '0502', 'PASS');
insert into table1 values (03, '20010104', '0503', 'FAIL');

insert into table1 values (05, '20010106', '0505', 'FAIL');
[code]...

I have tried the below mentioned query, whether any better query is there than this because in real-time data have 2 millions of record in table 1 and 60 thousand in table2.

select distinct a.id, a.join_date, a.join_time, a.status
from table1 a, table2 b
where a.id = b.id
and (a.id, a.join_date, a.join_time, a.status) not in (select b.id, b.join_date, b.join_time, b.status
from table2 b)
and a.id = (
select distinct a.id

Remove Constraints On Nested Table?

Jul 11, 2011

I want to truncate table partition but I'm getting error:

CODEORA-02266: unique/primary keys in table referenced by enabled foreign keys

because of table has a nested table. Currently this column is not in use so I could drop it, but I want to avoid it (table is huge). Is there another posibility to do truncate partitions in this table? ALTER TABLE ... SET UNUSED doesn't resolve the problem.

SQL & PL/SQL :: Remove Orphaned Records From Child Table

i guess "need to Remove the orphaned child records from the child table (foreign key relationship), and then re-execute the ALTER TABLE ENABLE CONSTRAINT command."

how to find orphaned child records from child table ?
